SWITCH BAR.

Application filed October 26, 1927.

This invention relates to improvements in railway switches and has particular reference to tie bars for switches.

An object of the present invention is to provide a bar by means of which the switch points may be positively connected, means being provided for eliminating danger of breakage or separation of the bar between the rails.

Another object of the invention is the prom vision of novel means for connecting the bar ith the switch stand.

Another object of the invention is the provision of a tie bar which may be used in connection with main line switches and block signal systems, as well as with side line switches.

With the above and other objects in view, the invention further includes the following novel ii'eatures and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing Figure 1 is a plan view showing a portion of a railway switch equipped with the invention.

Figures 2 and S are edge and bottom views respectively of the tie bar.

Figure 4 is an edge view partly in section showing an insulated tie bar for use with main line switches.

Figure 5 is a bottom plan view of the bar shown in Figure l.

Referring to the drawing in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates the points of an ordinary switch which are connected by a tie bar 11.

This bar is made from a single length of material in contradistinction to the ordinary form of tie bar which is formed of two sections and connected bymeans of a bolt at a point intermediate the switch points. latter provides a disadvantage in that the bolts shear off and break causing the sections of the tie bar to separate.

of a single length of material this serious 0b- Jection is overcome. In addition, the end of the bar adjacent the switch stand is bent upon itself so as to provide an inwardly extending hook 12 which is adapted to be closed by a bolt 13, so that a strong and positive conbar 11 and the switch stand.

If desired, the tie bar may be made in separate sections indicated at 1th and 15 in Figures 1 and 5 of the drawing. These sections have their adjacent ends insulated from one another as shown at 16 and are connected by connecting bars 17 through which pass bolts 18. The bars 17 are insulated from the bar sections 14 and 15 as shown at 19 and the bolts 18 are insulated both from the bar sections 15 and 16 and the bars 17. A strong and positively rigid connection is thus eiiected between the tie bar sections 14. and 15, so that in effect, a continuous tie bar is provided. The form of connection in addition permits of the use of the tie bar with main line switches and blocksignal systems.

The invention. is susceptible of various changes in its form, proportions and minor details otconstruction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. In combination with a railway switch, a tie bar adapted to be connected to the switch points, a curved inwardly extending h00k shaped extremity spaced from and parallel with one end of the bar and means eXtending transversely of the bar and hook-shaped extremity to close the end of the hook.

2. In combination with a railway switch, a tie bar made from a single length of material and including a curved inwardly extending hook-shaped extremity at one end of the bar, and means to close the end of the hook.

In testimony whereof I atliX my signature.
